Principled Volume coming to Blender!

As brecht says:

"Similar to the Principled BSDF, this should make it easier to set up volume materials. Smoke and fire can be rendererd with just a single principled volume node, the appropriate attributes will be automatically used when available.

• Color: scattering color. Multiplied with "color" attribute if available.
• Density: density of the volume. Multiplied with "density" attribute if available.
• Anisotropy: Henyey-Greenstein scattering anisotropy.
• Absorption Color: extra control over shadow/absorption color, separate from scattering color.
• Emission: emission strength.
• Emission Color: emission color modulation.
• Blackbody: blackbody emission intensity, for rendering fire.
• Blackbody Temperature: temperature in Kelvin. Affected by "flame" attribute if available.

There's still a bunch of TODO's, and no OSL or Eevee implementation, but it works well enough for early testing and feedback."
